将一种新型的ＣｕＭｎ催化剂用于由合成气合成甲酸甲酯和甲醇，该催化剂表现出良好的反应活性和甲酸甲酯选择性。考察了反应温度、合成气压力及催化剂制备方法等对合成甲酸甲酯和甲醇的反应活性及选择性的影响。在反应条件下，产物收率最高达６０．１０ｇ／（Ｌ·ｈ），产物甲酸甲酯的选择性很高。用ＢＥＴ、ＸＲＤ及ＸＰＳＡｕｇｅｒ等测试方法对催化剂的比表面、晶相组成以及铜、锰在催化剂中的价态进行了表征，并探讨了催化剂失活的原因。 A new type of Cu-Mn catalyst was used to synthesize methyl formate and methanol from syngas. The catalyst showed good reactivity and methyl formate selectivity. The effects of reaction temperature, pressure of synthesis gas and catalyst preparation on the reactivity and selectivity of synthetic methyl formate and methanol were investigated. Under the reaction conditions, the yield of the product is up to 60.10 g / (L · h), the selectivity of the product methyl formate is very high. The BET surface area, crystal phase composition and the valence of copper and manganese in the catalyst were characterized by BET, XRD and XPSAuger. The reason for the deactivation of the catalyst was also discussed.
